Very Bad Service!!!

Was contacted by Michelle in upgrades to inform me that I was due an upgrade (was on smart m contract, Blackberry) I told her that they can send me the Samsung Tab3. Tablet was delivered (without a sim card). On the 31/10/2015 got a message on my phone (Blackberry) that my phone was soft-locked, I could not make calls. I called the Vodacom Call Centre and was informed (after going through quite a few people) that I should be able to make call the next day. I am unable to make any calls from my phone. I called again and the automated system doesn't not give you an option to speak to a consultant, I had to explain my problem to numerous people who could not help me. I was told that the person who did the upgrade could assist me (Michelle). They assured me that they would get Michelle to call me back. Still no call, I then scheduled \a call back"on the Vodacom website. No one called. I then called again Friday 13/11/2015"
